carriage travels.

The chain miningmachines now generally.y

used have a stationary fra-meen which slides` the traveling frame thatcarries the cutting mechanismy including the' electric "inotorg The rearend `of the stationary frame is-.sup-` ported by a-i'loor rail, and is held yiin place,L

when ink operationY bya jack ony theforlr ward end of the frame which is forwardly braced against the'coal, and 'one at the rear a ,.end which's braced against thereof.r These Vjacks take the entirelth'rust `ofLthe'malchine independently of the `floor rail. The floor rail is used principally because it is easier to slide the machine sidewise yon the, rail than it would be ontheroughfloor. This methodfof placing the jacks isnot appli cable topiclrmacliines `becausc'a the forward jack is directly in front of the. machine and sois in the way of tliepicl. f` Also the rear jackie in the `way off the operator who usn-f ally sits behind the pick to direct it.

My method'is to hold lthe iioor frail inA place (preferablyby a couple ofjac'ks J, one on each side of thermachine, see ,Fignre 3) and to detachably attach the stationary frame or platform tothe floorfrail so that,y

the Hoor rail takes the recoil of the pick.

With the present pick? mining ymachine now generally usedl the recoil of the pick is taken principally by' a block on the foot of the machine operator which presses one of the machine wheels on ,the 'rear side and slides on the platform. The operator at the` same time slues the machine around on the `platform to the desired position.y This is Specification of Letters Patent. Applicationilei March `11, 1909. Serial No.482,750.

The rail-clamp has a gap on its lower side that straddles the floorrail 21 (see Fig.-
